I recently bought a new 960 evo 500 gb ssd and I had installed my os into my computer and updated the driver and everything. I have hdd connected to my pc. everytime i try to click things in my old hard drive i couldnt open it. it always has an error message that im missing somthing required to open that thing. Is my hdd can no longer be useful? what if i want to look back into it. how i get back to open up my data. is there a way that my old hdd can be useful?
